The procedure to measure PPM using MQ sensor is the same but few constant values will vary based on the type of MQ sensor used. Basically we need to look into the (Rs/Ro) VS PPM graph given in the datasheet (also shown below). The value of Ro is the value of resistance in fresh ...
From thedatasheetwe also get to have a formula for calculating the value of Rs. The formula is shown below. If you are interested to know how this formula is derived you can read throughjay con systems, I would also like to credit them in helping me to sort this out. In this formula...
